Mmm... falling fires, mediocre? I'm playing a game right now where one fire mage has killed over 70 enemy soldiers over just two battles just casting those, fireballs and incinerates. The visual results on the battlefield weren't stunning, but the numbers were actually pretty good. If you say about 30 enemy casualties per mage, 3 mages is nearly 100 dead enemy soldiers. Not bad, I'd say.

Cloud of death can be a very powerful spell, if you can hold enemy soldiers over one without yours taking too much collateral damage. Other cloud spells aren't quite as strong, but are still good against the right opponent.

Also things like that spell that sets large numbers of people on fire, and flame eruption if you can work it out, can cause large numbers of casualties. Most other spells work more indirectly and will result in your troops killing the enemies easier, which isn't bad at all but is a lot harder to quantify.

After that I can mainly think of spells that require gems, and if I recall correctly you are not very much into those.
